hi, i have to get another 1520 to replace my original one (broke the glass ) i went on ebay and found a baffling number of choices , some say "international" model the one i have is from att and has 16gig of storage. i went to wikipedia and they show 4 different versions with different specs. i remember when i ordered the first one from at&t there was a 32gig option for it but i diddnt get it at the time. i would like to get the 32gig version, but are they all the same? i am in the USA and use AT&T for a service. i was looking at the newer phones like the 950 XL but i feel i just need another 1520.even if i need to replace the battery i havent seen another WP that impresses me with the quality of the 1520. any help would be great, thank you.
