It's not something that your likely to see on a Blackberry device simply because of the long standing security protocols. But Android phones were hit with a Trojan that attached itself to legitimate applications. According to Lookout Mobile Security the malware is named Geinimi and is based primarily in the Chinese Android App Market.
Lookout claims that the malware has been "grafted" onto repackaged versions of legitimate applications, primarily games, and distributed in third-party Chinese Android app markets. Some of the games that Lookout has identified as being vulnerable to infection are: Monkey Jump 2, Sex Positions, Presidents vs. Aliens, City Defense and Baseball Stars 2010.
At this point the malware has only been found to be infecting the Chinese Android Market and as of yet has not been seen anywhere in the official Android App Stores. So if your sticking to Official Apps you should be ok. The best way to stay safe is as always to only download from trusted sources, only download official Apps, and be sure to check out developers names and user reviews for anything suspicious. Or you could always switch to a Blackberry :)
