I just got a cingular 7100g. Using it on the Rogers network in Canada...but I doubt that affects my attachment problem since the phone is unlocked.
I am running V.126.96.36.199 and the 'Open Attachment' option does not come up when I receive an attachment, thus I cannot open/view attachments. I am not using BES. Not luck with word, excel or jpg files?
If anyone can help it would be GREATLY appreciated
