Just another bit of useful info I've found out to prevent any shocks tomorrow during activation.
As well as the previous mentioned outcomes of the credit check
a) Activated - no problems
b) £100 Deposit needed [also note, this deposit is only held for 3 months then refunded]
c) Failed credit check
a fourth has now been introduced...
d) 'o2 needs more time to review your application for iPhone service.
apparently o2 will then contact you within 24 hours to go through some credit related things.
where did u see that?
