My sim is requesting me for my sim network pin..i dont know what to do please help me mr adeem.. :(

If your phone is asking for a "Network" pin it means your handset is locked onto a different network to that of your SIM card.
If this is the case, then you need to:
A) Get the handset "Unlocked"
B) Get a SIM card, relevant to the handsets carrier.
If the handset is simply asking for a PIN it may just be your SIM card PIN it requires.
If you didn't set a PIN on your SIM card the usual default pins are:
Unless you have a Wave SIM and that is different for every SIM
If you enter the PIN incorrectly after usually 3 attempts your SIM is blocked and you will need a PUK code to unlock it.
PUK codes can only be given by the SIM cards carrier (Service Provider) this means that you will have to call them and ask for it.
You will need either the SIM Card number (On the front of the SIM) or the SIMS mobile number.

lindipsy, it seems that the phone is asking you for your SIM's pin number. it should be written on it somewhere.
Usually 0000 or 1234 work, if there is no real SIM PIN number lock.

580i shut off and will not turn on

the firmware is corrupted. flash the phone (sometimes called debranding) I use not the cheapest but good support. follow the instructions to the letter takes about 10mins to do. see my other posts for more detail. will cost 10euros lots cheaper than getting it done by a shop & that is what they'll do anyway. use generic firmware rather than operator branded firmware. it will run better, & none of those nasty logos. furthermore any function that has been disabled by your operator will be restored (like switching off 3G or **** that you cant erase)after you've done this send MMS & Internet settings using SE website to complete the process. this can be done for free on BUT you have to put at least 20 posts on their forum so if time is an issue, dont bother. total gsm is an easier way if you've never done fone flashing before.
