My x50v was upgraded to wm5 since Dec 05.
I have some troubles with internet acess and data backup as well as active Sync.

First, it's the internet acess problems.
I have installed wm5 on 12 Dec, after a few days later.
I cannot see the default_axim.htm , it shows a white page just like about:blank .
So, I did a hard reset then the problems fixed.
But after a few days , the problems continued.

How can I do?

Second, it's data backup.
Before you do a hard reset , most of you would do a data backup on your Axim device. I'm doing so.
But I got a problem with data backup.
I restored the file after handreset, all Pim data should be restored.
When I sync with my computer, I got the same pim.
For example, I have 50 agenda and 26 contacts in X50v,
When I do Activesync , it gets 100 agenda and 53 contacts.(But the extra 50 and 26 are the same.

I need to spend so much time to delete the 'extra'.

I am using X50v/Wm5.
Is it better for me to downgrade the system to WM2003se or continue to use WM5?

Could you give me some suggestions?
