A word of warning to android users. Recently I changed my email address, My old one wasn't particularly suitable so I decided to start phasing it out and using my other one. I realised that I needed to change the account that was synced with my phone. I looked through all the settings and I couldn't find a way to do it I searched the internet and found a tutorial claiming that if you clear the data from google apps in application manager, you can then go back into sync options and input the new email details. So I did that, only when I input the detals and tried to connect, it said that it couldn't establish a reliable connection with the server, no matter what email I tried putting in. I searched this, and found that sometimes this happens to people who clear the google apps data and even to some people when they get the phone new. The only way around this is to do a hard factory reset.
So, after deciding to do a factory reset, I thought I should back up my data, so I downloaded and installed mybackup (which I had to do from my PC as you can't access the marketplace without an email registered) and I backed up my data and apps to the sd card ( I wasn't able to backup online it said there was some kind of database error). After resetting the phone, I installed mybackup and tried to restore everything only to be told that it couldn't retrieve the datastore. Luckily I had all my contacts backed up through wavesecure.
Moral of the story - changing your email address on Android is stupidly difficult and Mybackup is *****...
Also, can anyone recommend me a decent backup app for when I come to switch to 2.1
