Galaxy S4 - Will 32GB & 64GB be................

I just stopped into AT&T today to see about the GS4 and I will be stopping back when pre-orders go live (likely on that weekend when I have more time) and although I have 4 months left on my contract I am breaking free. Sometime next year I can then move my home connect line on Verizon to the AT&T version and reduce myself to data only on my iPads (we have 2) and that will be it.

AT&T confirmed they will be carrying the 16GB & 32GB but they have not heard anything at all about the 64GB so my guess is the exclusive on the HTC One 64GB was a trade off for them considering the non expandable memory (which is stupid they could have done it like they did for China). I was also told they are showing 4/26 as the launch date and that fits in the the rumored 4/24 date from Samsung. This is perfect timing and just before I leave on Vacation :)
 
Yes you can.... With AT&T they will assign a dummy phone number and initiate the port at the time of the order. When the SIM is put in the card (has to be done at the store) they will finish the port process. I did this with my mom who was on Verizon and I switched her to ATT. She was going from an iPhone 4S to an iPhone 5. The process was flawless and it was an impressive start to the world of AT&T and a big bye bye to Big Red.
