We get lots of chat questions as well as phone calls asking to confirm which phone they have. Here is a guide that will help you identify your phone.
If you look at the back of your phone there will be a model number. You can reference that to see which model your phone is:
iPhone Model GSM/CDMA Model #
iPhone 5 GSM A1428
iPhone 5 CDMA A1429
iPhone 4S A1387
iPhone 4 GSM A1332
iPhone 4 CDMA A1349
iPhone 3GS GSM A1303
iPhone 3G GSM A1241
iPhone 2G GSM A1203
*The difference between GSM/CDMA is this: GSM accepts a SIM card and CDMA does not. If you use AT&T or T-mobile, these are both GSM models. Verizon & Sprint are CDMA model.*
To find the capacity of your phone you can do the following:
Settings --> General --> About --> Capacity
We hope this helps! If you still have questions, you can still use the chat or give us a call!
