well one idea what you can do you is this...
sell your mogul on ebay as is hopefully get about 150 - 200 from your phone.
the touch pro is about 579.00
So take $75.00 off your phone
Your money u got from selling your phone 150.00
So you got $225.00 subtract that from 579.00 = $359.00
this is the other best idea...when i bought my mogul a year ago i just upgraded before the phone came out i think, and i got the upstage i sold that on ebay and got 170 from it. I got it for 400.00 on ebay and in the end i paid about $230.00 for my mogul and saved a few hundred dollars and i got it brand new and not used. let me know if this will work for you
