it's dependant on make (nokia/sagem), location and can even vary from box to box. it all comes down to what works best for you. Personally, i'm using Blade Trinity v2 which is spot on for me
It is a sagem and i life near the glasgow area, if anyone lifes near there or knows what is the best, im using blade 2 at the moment but my channels keep freezing.
If you know how to flash an image, try them all until you find one that suits you. Make a backup of your current image so you can flash it back on again in the future.
