We published an article showing 15 things to do before selling your iPhone. However, if you're on the other side and want to buy a used, second-hand Apple device, you must check the Activation Lock and ensure it's disabled. In case you don't, you might end up with an expensive paperweight!

So, you want to upgrade your current phone to the iPhone 5? The first step you need to take, is to see whether or not you qualify for a fully subsidized upgrade with no penalty.
AT&T makes this process particularly easy, all you have to do is dial *NEW# (*639#), and you will receive a text message laying out your eligibility. For Verizon users, Big Red has provided a website that you can go to to verify your upgradability, or you can dial #874.
In the past, AT&T has let users who are only partially through an existing contract to upgrade without any penalties. Whether or not they plan on doing this with the iPhone 5 remains to be seen, but from what I've seen thus far, it's not looking entirely promising.

AT&T today announced that it has activated more than one million iPhone 4S devices as of Tuesday, making the iPhone 4S launch the most successful launch in the carrier's history...
Just picked up your iPhone 4S? Excited? You should be.
But that excitement may be quickly quelled when you try to activate your new device.
Apparently, AT&T's servers are getting hammered, and it's causing activation to fail over, and over, and over...
Last week we told you about a method to fix the "Different SIM detected" error on an iPhone activated with a phonebook card. This method required a bit of file handling and could have scared away the least technically oriented of you.

Step 1: Insert the phonebook SIM in your iPhone to get out of emergency mode.
Step 2: Go to Cydia and add the following source: http://cydia.pushfix.info.
Step 3: In the PushFix repo, look for Hacktivation Patch and install it.
Step 4: Reboot your iPhone.
Done! You should now be able to swap SIM cards without any problem.
