Help! I have a iPhone 4 that worked perfectly until I upgraded a keyboard progam on Cydia when it suggested the upgrade. When it asked to restart springboard, I did and now it's stuck on the apple logo. Every ten minutes the spinning wheel also comes on. I've tried holding down the sleep and home buttons for ten seconds, using iTunes to do a restore, and still nothing I am a 40 year old mom of 5 and not the most 'techie" person,(quite proud of myself for actually jailbreaking it on my own!) and would appreciate any and all help! Thank you!!
