The alert features have also been totally overhauled and whereas it was a nightmare to get new alert tones, finally managed to easily get the 'Jack Bower 24' office phone ring' as my text alert...
Careful using Icloud to synch Outlook Calendar...It ended up creating an Icloud Calendar on my Laptop so I had the original Outlook Calendar as well as the Icloud Calendar both appearing in Outlook...it was a nightmare and it took me ages to remove the Icloud calendar and get back to normal. I like the Wifi Synch as each time I plug in the phone it automatically synchs with my laptop...no more USB. I have no use for Icloud other than the Find My Phone App which could prove useful if I lose my Iphone.
Yes...I Jail Broke my 3GS a couple of weeks back. The only issue with the untethered JB for IOS 5.0.1 is Ibooks is crashing when it's opened...solution...use another reader App. I switched over to the Kobo App as I have a Kobo reader as well.
