Hi, sorry for my ignorance.
Haven't unlocked a phone for many years now lol!
Basically all i want to do is unlock (for free if poss

) my new S5839i from the 3 network. Can I just check the following pls:-
1. Even if 'just' an unlock from netwk req, rooting has to be done?
2. Upon downloading the zip file to my laptop/pc (to root the phne), i need to get this zip file or the unzipped file copied to my SD card?
your help is appreciated
==========================================
Hurrah, finally able to make calls from the phone.
Followed following procedure:
a) eventually got root zip file for 2.3.6 gingerbread, copied to SD on phone
b) downloaded following apps (though still unsure whether needed them all!):-
super su
busy box
galaxy ace unlock
galaxy toolbox
Though unsure as to whether it was the 'Galaxy Ace Unlock' - (unlikely as displayed "....unlock code is one of these codes: or or or ...") or
'galaxy toolbox' that unlocked the phone
However, although i can now make calls from the hone with my o2 sim (prev locked to three network).
I cannot access the internet (have allowance with o2) have had look at network settings and all looks good, any ideas please?
also still has the not so lvly 'three' splash screen upon start up (just after sams 'gal ace GT-S5839i' splash and just before main 'samsung' splash)
would appreciate help please re internet access and getting rid of three logos?
