jacobsaa,
Go to the t-mobile 7230 system upgrade page.
http://www.t-mobile.com/products/han...load_popup.asp
Enter your phone number and download the two files.
(Desktop 4.0.0.30 and OS 4.0.0.185)
Install the desktop program first. Next run the t-mo40.exe file.
Follow the onscreen prompts and away you go. It should take about 10-15 minutes for a full backup and install.
All of your information will be retained. Some of the address fields have changed in 4.0, so you may have to move a work address to a home address. Little things like that.
There will be some changes that need to be made if you're using the BWC for e-mail. Tmoobile defaults to the desktop as the e-mail system.
You will change this in 2 places.
1st - Options/Message Services/Change Option to Web Client
2nd - Messages/Options/Email Reconciliation/Message Services/Change Option to Web Client
Other than that it should be pretty seamless.
Let us know how it works out.
