I am considering on purchasing my first Android device. I am currently on a T-Mobile Prepaid Plan right now with a old Blackberry 7100t. I currently subscribe to no data plan - and am going to probably remain without one on my next phone. I noticed that T-Mobile has a new Android Device for Prepaid called the Comet. Amazon sells it for around $150 - which sounds reasonable. I understand that it won't be blazing fast. They also sell an unlocked International LG Optimus GT540 for around $190. The version that is included with the Optimus is only 1.6. It looks like I can upgrade it to 2.2. But, I will have to download it from the LG UK Site. I also hear that it is difficult or impossible to ever get data on the Optimus. So, if I were to ever want data, it'd be hard to do. What would be better? Thanks for your help!
