1. I installed many games from this forum, but when I play the game, my screen always flashing. I don't know what's wrong.

2. When I use media player to run *. dvi, it only game me sound but no images, so I wondering if I could install another software that I could play more formats.

3. I don't have data plan, so I wondering if I could use wi-fi to check emails from any software. (expect to access my mailbox through website)

Thank you so much if you guys could help me or give me any suggestion regarding any of these three questions.

Thanks so much!

1. your game is likely no compatible with a BB.

2. unfortunately not, i dont know of any 3rd party media players for the BB. however you can change the extension i.e. divx to avi and it will play normally on a pc, it may then play better on a BB.

3. possibly.

thank you so much!

For push email, you must have a BB data plan. you might be able to check it via a webmail account, but not using the BB's email functions.
