Does the sim card need to be in the Iphone(all the time) just to make it work

[yamibg]

after its been jailbroken, if its OTB(1.1.2)?

[phillyphill39]

no, if you want to use it as a movie player, or an ipod then no.

i have a go phone that i use when i do construction work sometimes... and i take out the sim from the iphone and put it in my go phone, my brother uses my iphone as a [thinker] iopd touch while im gone

The only things that will not work when the SIM is out:
Phone Calls
Texting
EDGE

Your carrier logo will also say 'NO SIM'
