Blackberry email forwarding from Gmail to blackberry using yahoo doesn't work well
see updated post above why the folllowing below doesn't workwell
The post below falls true if you forward your gmail to your tmobile blackberry:
PROBLEM: When mail bounces when sent to tmo.blackberry.net if its over 5mb. Then gmail filters stop forwarding that email to your tmo.blackberry.net. You stop receiving your mail and have to log on at a computer to 'try again' the filters to make it work.
SOLUTION:
Use Yahoo!'s new free push mail to tmobile.
You would use the same filtering techniques as described above. But forward your g-mail to your yahoo email. Then set up a pop account at www.tmobile.com to your blackberry.
Note: when you set up the pop for yahoo, you can use any address that is legitmately yours. It doesn't have to be the yahoo address.. e.g. you can use my8700@gmail.com
