I am getting word that there is a TCP/IP stack on a Verizon BlackBerry 7250 but not
on a Bell Mobility BlackBerry 7250. (i.e. disabled by Bell Mobility)
Does third party applications (VeriChat, Reqwireless, etc) work on your 7250?
To test, you can install VeriChat MSN / AIM / ICQ by typing this web address into the BlackBerry Internet Browser (not WAP browser)
This will wirelessly download and install Verichat software onto your BlackBerry, which you can use to log into instant messaging on your 7250.
Also if your BlackBerry Internet Browser is missing, check out:
