Hi all! I'm new, by a week, to the Android community! I received as an early Christmas present, a Samsung Galaxy Tablet. I am in love! I've been working on it every day for 2 hours per day; need it for work and want to be fully aware of what it can do when my season starts again. (unemployed landscaper). Question: I now want to upgrade to an Android smart phone. I've done my homework on cnet and digitaltrends and I read that AT & T (my carrier) has the WORST of the Android phones. Sprint and Verizon: either the EVO or Samsung Epic. If I can find these phones on ebay, can I insert my AT & T sim card and have them work? I really don't want to trade off AT & T (been with them 13 years, no problems) but I also don't want to buy the "dog" of an Android phone that cnet hates. ANY advice would be appreciated and helpful!
