if I still had my inc, I would be holding out for a better selection. I got an inc2 through an insurance claim, but otherwise I wouldn't upgrate right now. I sell phones all day, so heres my reasoning:
The Tbolt, since all the recent updates, has turned into a pretty solid phone, however its nearing EOL (end of life) and HTC had a phone pass through the FTC or whatever that will be the replacement and it looks like a beast.
The Charge, eh. Never been impressed with Samsung phones. There is always a ton of hype around em, but honestly, their UI is clunky and they are horrible at updating their phones to the newer versions of android OS.
LG Revolution. Lowest priced 4g phone, you get what you pay for. Have had a ton of issues with the few of them we have sold and honestly, my store has pretty much vowed to not sell any more of them. Software and hardware issues galore. Not to mention its already almost EOL with LG announcing the Revolution 2 coming out in the fall.
The incredible2. What can I say? I love it. Battery life is easily twice what the original inc. a little bigger screen, front camera (which I don't use, lmao) and very solid performance. Great overall phone, no doubt about it. Most solid phone we carry right now. However, its really not a big upgrade from the original inc.
droid x2. Meh, moto has/had some software issues to figure out cuz that phone, along with the droid 3 are buggy as hell.
honestly, wait till the end of october. By then we should have all the new phones in tow (including the Bionic which launches next week) and you will be able to get a pretty significant upgrade (hopefully) over the original inc.
