I posted a link in another Touch Pro thread to slickdeals where you can get a Touch Pro for $49.99. You have to be eligible for a $75 or $150 upgrade. You get to keep your plan except for SERO.
I ordered mine and got it within 10 days. It comes out even better than having Sprint replacing your TP1 because you get to keep it and sell it later. So you actually can make money on the upgrade.
No reason to bang you head against Sprint CS or service centers. Give it a try.

(if you are opening a new line of service, PM me and we can both get a $25 credit)
