Solution for EDGE settings not saving on v1.1.2
Ok. Firstly, I doubt this is a widespread problem, but if you swap sims on an unlocked 1.1.2 you have to re-enter the edge settings and since I use a hypersim with the dualsim, it was a MAJOR annoyance to me.
To overcome it I used Winscp in windows (I rat it using parallels desktop) to get into the phone then navigate to the following file:
Right click and check properties to find where it links to. Mine linked to another linked file:
Now, what I realise is that that number is the MCC+MNC of my operator here in Jamaica, so I figure it will link to the MCC +MNC of your carrier. Anyhow, as I said, this is also a linked file which links to:
I tried editing that but the settings wouldnt stay, so I examined the O2_UK file and realised the differences, did some editing and made a plist file for my operator Digicel and named it DIGICEL_JM the contents of which is below:
I then created a link file to DIGICEL_JM and named the link file 338050 replacing the one that was originally there, I reinserted my sim and my edge settings were there automatically :)

You can create your own by changing the relevant info that applies to you.
Hopefully this info isnt new and hopefully someone can write a better guide than I did, yeah, i know I suck at this lol.
Anyhow, later dudes
