For your O2 device to function properly, both main and backup
battery MUST be full, or the main battery promptly recharged.
Otherwise, it will trigger itself into a Hard Reset, resulting in
total lost of all settings and data stored in ROM.
Ideally, you'd be better off upgrading to an O2 Atom Exec, or
Stealth or even the latest Zinc, which runs Windows Mobile 5 which
is much more stable.
Coming soon is the O2 Xda Atom Life, it boasts a 620Mhz processor,
and 1Gb of ROM size.
Price of Xda Zinc is around $1,300.00
Personally, I'm using the following in rotation:
> Atom Pure
> Atom Exec
> Stealth
Just orered the Xda Zinc and Atom Life.
