I bought a Storm from Vodafone last Saturday. As I was porting my number it didn't become fully active until Wednesday.
On the whole, I'm happy with the fone. HOWEVER!!!!! There is currently a serious problem with the battery life. It sucks. Driving home from London, a full charge lasted just over 3 hours. I had bluetooth turned on for my handsfree kit and made approx 5-10 minutes worth of calls.
Checking the Vodafone forums this is an issue a lot of people are having but is is believed to be a firmware issue as the pre-release versions didn't suffer with it.
So, I'm desperately awaiting the firmware release to resolve this.
