iPhone question. We just got a used iPhone from an in law, it's a few years old.
1. How can I tell what model # it is? There is a serial number on the back, but nothing that says iPhone 1, or iPhone 2, or something like that.
2. In updating the IOS, it updates to 3.1.3 and says that is the most recent IOS for this phone. The most recent iPhone IOS is 5.x, shouldn't this phone update to 5.x, or do the older iPhones not get supported in the IOS upgrades.
It's odd because the Skype app won't load because it says it's incompatible with this iPhone.
They all have cameras in the back. I do not know what the number means. I have an old 3 I am giving to my grandson, and it has MB70something on the back. If it won't run some of the updates it is probably the original. Download itunes to your computer if you have not done so, and register this phone.
