Well, I was able to gather that EJ's cell phone is through Cricket, opened account on 12/21 with $44 using the 78249 zip code
I don't know exactly where to post this, it's not quite a tip, but it's background on Cricket service for those that may be unfamiliar with this carrier.
Cricket provides two forms of prepaid service, pay by the month for unlimited service or you pay by the day on the days you use it with the Cricket PAYGo plan. Neither plan requires a deposit or a credit check. Generally speaking, when you buy a new phone from them, you get the first month of service for free. They've been offering a refurbed Samsung for 9.99 for the past few months and have also been sporadically offering deals on their unlimited monthly service that start at 25 dollars. Their deals change frequently, so the plans you see on their site today may not be what was offered in December.
It is very difficult, if not impossible for most people to use a non-Cricket phone with Cricket. Phones like the iPhone can not be used with Cricket. Cricket is part of the CDMA network.
"Of the U.S. carriers, AT&T and T-Mobile use GSM while Sprint, Verizon, and smaller carriers such as such as MetroPCS and U.S. Cellular use CDMA." From
http://reviews.cnet.com/cell-phone-buying-guide/ However,you can use old Cricket phones for their service. Let's say I stopped service on my Cricket and gave it to my neighbor, he could then take it into a local Cricket store and get service in his name. Or, if I took my Cricket phone to another state, I could use it to get service in that state.
(Edited because TPS did not buy an iPhone on ebay, looks like she bought an iPod touch.)
About the charger supposedly found in EJ's room.. Cricket sells a phone, the TXTM8, that apparently uses the same charger as the "Apple iPhone 1st Genration, iPhone 3G, iPhone 3G S / iPod Touch 1st, 2nd Generation".

Maybe she was using the iPod charger to charge her TXTM8.
