If I buy a T-Mobile Sidekick 3 off eBay or something, is there anyway to activate it by the means of prepaid with the whole text, aim, and internet browsing thing because I know on the website it says you can do it for like 20 bucks, but thats only if you are on a plan. I know with like Verizon or Sprint you need the ESN HEX and ESN DEC number just because I work at Best Buy with all the phones.
OR
If I could just get a Sidekick, and put a Cingular SIM card in it and then just use all the features that the Sidekick can do such as AIM and the internet browsing. I read in some places that you can't because T-Mobile has certain towers that are specifically designed for the internet, but other places said it should be fine because the phone would just use Cingular towers. Help?
Thanks.
