Ok, decided to upgrade my o2 xda exec to windows mobile 6 with an unofficial rom from xda developers.
Get it here Jwrightmcps Crossbow ROM Update 2.12.08 WWE
I first made sure to check all known potential hiccups with this rom. I then backedup my stuff and started the simple RUU tool provided. I waited for 15mins and then ......IT WORKED!
I have been adding apps etc all night and have found everything works a treat. This is an excellent upgrade. Everything working fast.
Happy I did this. If you have an o2 xda exec.....do it!
