1 - This thing has been 'tested' on the Vodafone Smart/Huawei U8160 insofar as plenty of people (myself included) used it with our devices to unlock their full potential
2 - This recovery image has absolutely nothing to do with the ROMs day-to-day life whatsoever,unless you frak-up the install and brick your device
2.5 - As far as I could tell from the rather odd mention of 'broken telephony' that you stumbled upon the very early ICS build that's been kindly done by subpsyke from MadTeam. As it's plainly stated - it's a T E S T build,so don't flash it until it's stable,which won't be anytime soon... Plus you can't flash it with this recovery
3 - Regarding rooting,Installing the recovery and flashing a ROM - Again,I really don't think that it's a good idea for you to do that until you're capable of at least rooting your device... And before you ask - there are guides even in the Vodafone Smart section here at MoDaCo + There's a thing called google,too...
