I've spent the last couple of days upgrading Mac OS X to 10.7.2 on five Macs and putting IOS 5 on my iPad 2 and iPod Touch. A completely painless operation, albeit a tad slow due to the enormous demand on Apple's servers. I also updated a couple of ATV2s.
Having closely followed the Apple Communities it looked like a process that would be fraught with problems! However, I always remember that only people with problems post, and there were plenty of them.
My SIM free iPhone 4S arrived this morning and it was a simple migration from my 3G. I used a SIM cutter to chop my original SIM to size.
I like the new feature in IOS 5 and Siri is rather fun. Unfortunately iCloud is unstable due to load but will hopefully settle down. It has some really nice features.
