I'm planning on changing carriers and I'm looking into T-mobile (no annual contract plan). I'm a noob so please bare with me. Would it be safe to say that with T-mobile's recent acquisition of MetroPCS, I should be looking for a phone that can receive HSPA+ and 4GLTE? I read that T-mobile wants to roll out its LTE service in the 1st quarter of 2013. I'm figuring with the Metro buy it will get the ball rolling even quicker. Their HSPA+ isn't going anywhere and seems to be plenty quick enough in the LA area from what I've read. I just want to future proof myself with this purchase since I'm not the kind that needs to swap out phones every year or two. It seems that there are only a couple of phones on T-mobile's site that have the capabilities of HPSA+/LTE. The Galaxy S3 being one and I can't remember the other off hand. But my problem is they are not offered in the prepaid plans section. Are there any other phones that can utilize both HSPA+ and LTE and be used with T-mobile? Unlocked AT&T phones maybe?
