Question So close, I could cry.... Begging for my ARC to be Rooted!

Hi Folks

I'm sick of all the bloat-ware on my Sony Arc (Purchased last Aug). I've recently had the phone unlocked and for the life of me, I can't root the damn thing. I've spent the last few days, trawling through all the helpful posts on this site (very informative and top notch stuff), but no matter what I try, the links on the posts are either no longer valid, the exploits have now been patched or my firmware is not listed.

Please, please, please, can someone give me a "Dummie's Guide" on how to root my phone.

My Arc is running Version : 2.3.4, Build Number : 4.0.2.A.0.62

Incidentally, just in case anyone is wondering, if I switch the phone off, hold down the menu key and connect to the USB, my phone displays the little blue led.

The closest I've came to successfully rooting (from my numerous attempts on here) was a simple click systems screen by DoomLord. My phone seemed to take to the program and then rebooted fine, but it still wasn't rooted. I've enabled USB Debugging and enabled unknown sources, etc.

This is driving me crazy. Can anyone help, please?
