Hello. I bought a bad ESN iPhone 4 CDMA on Craigslist (was going to buy an iPod Touch, but the iPhone was cheaper). I was able to activate it in Mexico, and now I sold it. I wanted to try Android, and now I have the Samsung Galaxy S3 on prepaid. I have the 30 dollar plan with unlimited text and data (5gb at 4g speed) and 100 talk time. I've been happy with the Galaxy S3, and it feels faster than the iPhone 4. I really love the front facing camera, but DON'T like the music player! I have downloaded many music players, and they all sound low compared to the iPhone 4. The music alone is making me want to go back to the iPhone. A guy wanted to trade my Samsung Galaxy S3 for their iPhone 4s 64gb, and I said no because I would be on edge. I just checked the sightings of T-Mobile 3G coverage on 1900MHz, and a lot have been appearing in LA! I'm starting to regret it. Would you trade for an iPhone 4s 64gb? Is anyone using their iPhone on T-Mobile prepaid? Would you recommend keeping the S3? I would looove to buy the iPhone 5, but I would have to buy it unlocked. It's too expensive for me now.
