honestly, i haven't had any problems with any apps messing up my phone. I prob have tried out about 40 different apps. Some are awesome and some are just plain horrible. If you look at the ratings and user comments, usually someone has already dled it and reviewed it. But I haven't really had any problems myself.
One thing I will say... I have an iPod Touch, and the apple apps are def better than the android apps. But thats just because the iTunes apps have been around for years and the Android apps have been around for months. In time this will even out.
Actually Android has been around for years not months.. Just because nobody has heard of it til it came to Verizon doesnt mean its new. I think alot of people that prefer the Iphone over Android dont really know anything about Android.
