Firstly I'd just like to say I'm not making any money out of this or spamming, I'm totally genuine and doing this because its a genuinly good thing.
If you've got the latest firmware updates from SE then it is possible to put a customised Android 2.3.3 ROM onto your system. You will see just how bad the stock SE interface is once you've been using the new one. You will get multi-touch, and most important of all, be able to put your apps onto your SD card in a very easy way.
I've written a guide on how to do it, just click on the following link and follow the instructions carefully.

A Word of Warning - If you decide to do this (and I think you should) you do so at your own risk, neither myself or any of the rom developers will be responsible. However there is a lot of online support. The worst you can do is have to re-install the SE stock software using the SEUS.
Like I say, its well worth it, if you like to tinkle with your phone then this update will make it uber uber sexy.
