I've now got rid of my Samsung F480 and got myself a nice HTC Tattoo. The main reason I got rid of the F480 is because A. the touchscreen had stopped working and B. I completely destroyed the phone trying to get it into another chassis!

I'm liking the Tattoo which runs Android 1.6. One thing that is annoying though is the amount Orange seem to have customized it and the fact that not a lot of applications in the Android marketplace support QVGA. This means they are just not available. Apparently more VGA Android devices will be out soon so support should increase.

Anyway...

Here are a couple of interesting sites I've found along with apps to customise your phone.

Jordan over at samsungflashwiki has managed to get some screen shots of the new open platform from Samsung known as 'bada'. It looks like developers can get involved and make their own apps for Samsung devices which is a much better idea than the current widgets. It doesn't look like it's going to beat the iPhone or Android but its nice to have another option which is probably cheaper as well. Take a look at the links below for more info!

I was having some dreaded BSOD problems recently and managed to narrow my problem down to my USB device by doing the following so hopefully this will be useful for you too!

I didn't want to bother with using the command line so this method gives you a quick idea of the problem and you only need to install one tool.

Revlin software have been very quiet about their new OS for the F480 and their Android port. Nobody seems to be able to get much info out of them either. Some people even believe its a scam so take a look at these links (translated from Dutch).

As 'japie' has said on the Revlin site 'Don't believe the HYPE!'.
