leobg,
GlobalNwSwitch.apk is included in the Rom tool, but that wont make GSM show up in the settings menu (menu>settings>wireless&networks>GSM/UMTS Options), I think that is part of the settings.apk or settingsprovider.apk But if you go to the testing menu (*#*#4636#*#*), it will let you enable GSM through there, I just dont know if that is enough to make calls.
Let me know if you end up giving it a shot.
and to 473x15,
The Alpha is still up, I guess it was more of a proof of concept for the D2G_Rom-er. I suppose I could manually port all the D2 Roms, but that would involve getting lots of permission from The Devs that poured heart and soul into making them, and since the sensors don't work, it would be a huge waste of my time. WoZzy talked to Squildly and go the ok, so we released it.
I've talked to the Liberty Devs, and while they would probably have allowed me to release their ROM (broken as it may be), I got the feeling that they would much prefer an official, fully functional release. And rightfully so, they don't need to be providing support for our hacks/mods. So, that one wont be released unless we work out all the bugs.
Which reminds me, if anybody tries a D2 ROM, don't complain to the original dev that the sensors are broken, it's not their problem. And if you do enjoy running a D2 Rom on your D2G, please take the time to thank the D2 Rom Devs! They've put in a lot of work and deserve all the credit.
This rom tool accomplishes two things, first it took quite a lot of time, and several SBF's to figure out which libraries we need on D2G to run a D2 Rom, rather than asking everybody to do that manually so they can help figure out sensors, this tool makes much quicker work of it. And second, it does allow people itchin to try Roms to do just that (even if the sensors are broken for now). If I, or anyone else who cares to take a crack at it, figure out the sensors, then we'll take the time to talk to real dev's about porting their work to the D2G. For now, D2G users can get pretty good functionality with all the Themes, as long as they can live without sensors (which does kinda suck, but really isn't that bad of an experiences...I've been running with out them for well over a week now).
