vCardIO is a utility to import/export contacts from/to a vCard (vcf) file on the SD Card. The vCard parser is based on Funambol code.

The currently supported vCard version is 2.1 (for both import and export). Currently supported fields are phones, contact methods and photos. vCardIO does not sync contact data, however it can remember previously exported or imported contacts and either completely replace them or ignore them on import.

Droid gives two numbers as hint. One is indicated as “+” and the other is “-“. The “+” indicates the number of digits known at the same place with the original number. The “-” indicates the number of digits known at the wrong place with the original number.

DealDroid is small application for Android devices that continuously watches for new deals on one-deal-at-a-time sites like BonkTown, Brociety, ChainLove, Steep and Cheap, Tramdock, Whiskey Militia, Woot and associated sites, ThingFling, and SlickDeals. DealDroid runs in the background and produces Android notifications when new items become available.

You can configure how aggressively the software will search for new items, as frequent background updates and keeping the phone awake may decrease battery life a bit. Although, I have not noticed any significant battery drain on my G1 using a 2 minute check interval.

Currently, DealDroid supports all of BackCountry.com’s one-deal-at-a-time sites and a few others that I find interesting. More sites are on the way in future versions. If there is a site you’d like added, please open an issue on Google Code.
