Flashing/Unlocking solutions

undefinedHello, I am a total newbie looking for some help please!!
I am looking at repairing all makes of phones, What is the best solution for having both capabilities (Flashing & Unlocking) Are the Superclips/Griffins capable of both etc. Would like to keep things as simple as possible to eliminate having to buy excessive cables! I do not really need remote capability ie can work from my PC!

Any info/advice would be greatly appreciated as I would like to get things right from the start!

Cheers!!

Did You Ever Get Sorted Out I Would Say Data One Then A Smart Clip But This Do Not Flash Also The Data One Is Not Getting Any More Upgrades!! Sorry I Cant Help With Flash Files And Flashing Phones I Have Little Knowledge On That
