i wiped the content on my phone to go back to factory settings and now it isnt being recognised by itunes. i have put my sim in it, but that too isnt being found. there is a little padlock symbol on the screen above the connect to itunes picture/logo, i am wondering if perhaps i should have taken my 3g phone off of password control before wiping. could this be the reason? and if so, what can i do about it now? please someone, i really need your advice. thanks susan.
