Ok, so I updated to 4.7.0.99 and so far this has fixed my problems with the storm. If anyone else is having problems with the blackberry storm then I would suggest you download and update to 4.7.0.99 as it is by far a HUGE improvement over existing releases for the blackberry storm.
I have it uploaded on my home page. You can have a direct link of 4.7.0.99 here. You will get better battery life, better signal and snappier response along with the stability issues seem to have been resolved. Please bear in mind that this is a BETA release, so use it at your own risk.
