I thought the exact same thing (not this quote but the post before when you said "4.3 is too big"). I had the DINC since launch and when i bought the T-bolt i was afraid of the size. Now my t-bolt is almost too small. I can't even hold a DINC anymore. I gave it to my friend and everytime i take it i can't beleive i used something that small.
Trust me!!! the 4.3 is perfect size. you will never go back once you get used to it. and it only takes 2 days to get used to. anything bigger is not good though (G-Nex). 4.3 is perfect....... Again, i was exactly like you before i got it.
I plan to go down to the local store and check it out when it comes out. I want to find out though... You have 2 weeks to return it from what I understand. IF I decided I wanted to try it out, I would have to cash in my upgrade to get it, with a new 2 year contract. If I decided I did not want to go with that phone am I still locked into a 2 year contract, but I just now get to pick yet a different phone. Or can I go back to my Inc and still still have my upgrade and not be under contract?
