i recently updated my iphone 3g. when updating the iphone an error came up on my computer screen and my iphone was in the "slide for emergency" mode until i plugged it in to another computer where it returned to normal. all my apps and music had been deleted off my phone (as i expected) but when i plug it in to my computer itunes just says: " itunes could not connect to the iphone because an invalid response was recieved from the device." is there anyway i can get my apps and music back on to my phone and get itunes to recognise my phone??????????????????????????????
