Need an I-Phone for work.

Recently came to a decision to get out of the delivery buisness on bikes,due to aiming for the high wage but risky areas of I usually get involved in,just came to the conclusion - got plans and want to be around to carry them out.
There was one area I have'nt done on 2 wheels an that's food delivery.
Theres an up an coming restaurant in North London,that wants me to head up a fledgling fleet of riders,so i'm going to need an I-phone strickly for work,to which i'll be looking about for tommorow,as formalising work placement starts fri.when i've been invited to come an oversea operation an advise them to get the ball running c/mon.
Employer wants GPS,which i'll assume is something akin to the low-jacking I had on my last job i'll be working,advising,riding 12 hour days 5-6 days a week,split shift daily's,so looking at specs/reckon I-phone 5 with a 10 hour? run time,probs. on a 24 month contract as reckon that will be last orders for this type of work,before I move into retirement job plan (utility vehicles).

 

Major superstore 5 min.away.....by bike,grrrrr -
however,after fri.visit to sitch in North London,find out if I wanna head in that direction/sorting Oyster for it,so may fire down there.

How the f..k,did you know,i had a 24 month timeline going.??.
