My phone is broken and my friend just gave me an old sprint blackberry of hers to use -- how can i switch my number to the bberry? do i have to call customer service or is there an easy way for me to do this online?
If you already have a Blackberry plan, you should be able to switch to the old blackberry. Just log in to My Sprint with Firefox, click the 'I Want To' by the device you need to change and choose 'Change Device'.
If you don't already have a Blackberry plan, I'd suggest calling customer care. The online plan swap tool isn't 100% yet and may cause you grief.
