Now, you are ready to connect. Click the Connect button. If you see any error messages, follow the directions, or contact your wireless carrier for setup assistance.

Locate the ip_modem_configuration.xml file. It is probably best to use the Windows search feature or Google Desktop to find this file, but you may find it in one of these places:

• Vista: C:\ProgramData\Research In Motion\BlackBerry

• Windows XP: C:\Documents and Settings\All Users\Application Data\Research in Motion\BlackBerry

Open the file using a text-only editor such as Windows Notepad or Wordpad.

Locate your wireless carrier's name. Take note that carrier names with ampersands like AT&T will be listed as "AT&T".

Change enabled="false" to enabled="true" as shown in Figure 5.
