I've been reading about supposedly improved radios for the SIII too but haven't found the source of the information. So far it's just people saying it in a few forums.
I got an interesting text this morning saying it's my last chance to get a $100 discount to upgrade to ANY 4G phone. Didn't even know I had a discount coming to me, sneaky VZW. Here's the full text.
FREE Verizon msg: Exclusive Offer! Last chance to Upgrade EARLY and get $100 off ANY new 4G LTE Smartphone! Plus, get a 4GB Smartphone data plan for only $30 monthly access! New 2yr agreement & data pak req'd. $30 upgrade fee will apply. Offer ends soon, so call 800.***.**** today! Reply X to stop msgs
I think my hands are tied on what to upgrade to. I'll probably be going with the S3 though I would have liked to see what the Fighter/RazrHD is all about first. Oh well, such is life.
