Cc:Betty, a free service that helps organize group email threads, has rolled out an iPhone app to help declutter your email on your mobile device. Cc:Betty’s app is a group based email application that breaks email conversations into collated, threaded discussions.

An account can be created right from the app, and new group discussions can be created, using the iPhone address book to access your contacts. Photos can be easily attached as well and new contacts can be added to discussions via your address book. Any discussions, or other content such as attachments a person has in their Cc:Betty.com account are automatically synced to their iPhone. When one of your discussions is updated, you’ll get a push-notification to your iPhone so you can access important information on the go.

Founded in 2008 by Michael Cerda, Cc:Betty began as a web application that routes, parses, and organizes email conversations in a simple at-a-glance dashboard so you never have to scour your inbox to find the bits and pieces of a long thread. If you cc “betty@ccbetty.com” on any email, “she” will create a mailspace, which is a webpage, for your entire email thread and will divide important things such as dates, times, people, places, and files and will format them all in one place. Cc:Betty will track messages with up to 100 recipients and can organize emails with up to 20 MB in size, including attachments.

Cc:Betty recently integrated with Twitter, so that users of the service can tweet in and out of a of the collaboration platform, as well as see each other’s latest tweets. The startup also upgraded its service with several new features, including the ability to see maps, images and documents as large thumbnails in email threads, and a list of people in an email conversation. You can also filter content of the thread by participant. The startup’s founder Michael Cerda tells me that the company is also rolling out a stealth SMB centric offering in the near future called Threadbox.

The startup also just raised $500,000 in funding from Western Technology Investment. The startup previously raised $1.5 million in seed funding in June led by Venrock with investors Seraph Group and Hillsven participating. The company was incubated in Venrock’s offices and officially launched at DEMO in March.

As the way consumers read books evolves, there is an opportunity for mobile technologies to connect consumers with their favorite reads. Mobile Roadie, a startup that helps develops iPhone apps, is collaborating with one of the most foremost publishers, Random House, to launch iPhone apps for authors.

The Random House group will launch free individual iPhone applications, powered by Mobile Roadie, for three of its bestselling authors—Steve Berry, Sophie Kinsella, and Karen Marie Monin. With this new application, fans will be able to preview books, access bonus content, interact with other fans, check upcoming author appearances, listen to audiobook clips, watch author videos and book trailers, and more.

Mobile Roadie also developed the official iPhone app for LeWeb, the foremost European technology conference organized by French entrepreneur and Seesmic founder, Loic Le Meur and his wife, Geraldine. The app was a huge hit at the conference.

Mobile Roadie only offers iPhone apps but will soon offer the ability to develop apps for the Andoid in January. The beauty of Mobile Roadie’s platform is that it offers a dead simple mostly-automated system to build apps and have them posted to Apple’s App Store in as little as a week. Launched earlier this year, the startup develops mobile apps for other conferences, events, and venues, as well as musicians, athletes, politicians, and other celebrities.

• Spotify Gets A New Mobile Savvy CTO

Last month, we wrote about the VoIP startup Jajah being the target of a bidding war. Today, it appears that war is over, with the winner being O2, and the price being $200 million, according to a report sent out by the financial website TheMarker, and being circulated by Reuters.

It was believed that Microsoft and Cisco were two other companies that were vying to get the company. Back in June, the company served up its 1 billionth VoIP call. While the company has some 15 million subscribers of its own, many of the calls originate from Yahoo Messenger, which has used Jajah since 2008 for its VoIP calls. They also have a deal in place with Microsoft.

The company has raised over $30 million in funding over four rounds. They are backed by the likes of Sequoia and Intel Capital. O2 is the mobile arm of Telefónica Europe, and had been considered the company with only an outside shot at theacquisition, especially considering Microsoft’s partnership with Jajah. Earlier reports indicated the price could be driven as high as $400 million in a bidding war, instead it appears to have stayed on the low side.

We’ve reached out to Jajah for comment on the matter, and will update when we hear back.

• “Ask A VC” Guest Swap: Kopelman Out; Hirshland In

Oskar Stål has joined Spotify as its new CTO after the departure of the original CTO Andreas Ehn, who left to pursue his own startup. I guess people slightly forget that next year Spotify is actually going to be 4 years old, even though it only launched publicly at the end of last year. (Long time in private beta).

Stål comes from the mobile transaction company mBlox, where he’s been for the last eight years, growing from a five-person start-up into a global business.

By hiring a CTO with deep mobile experience it’s clear Spotify sees the mobile as the key supporting plank in its structure. Last night I spoke to a Spotify contact who told me that since they launched the Symbian version of Spotify, the service has “gone crazy.” Make of that what you will. Symbian, as a platform used by Nokia’s non-smartphones, is of course a great deal more mainstream, especially in Europe, than the iPhone or Android.
