Still those of us with T-Mobile wanting to use Jump! have no clue what's going on...
Hopefully T-Mo sends out a mailer of their own.
Took me a while myself to figure out everything. If you have jump you can't pre order online needs to be done in store on the 19th. Best bet can how I'm going about things.... You can either pay off your eip... Or upgrade without jump but you will be paying 2 eip's monthly
