why can't i log into my gmail account from my New iPad

How did you set up your Account?

I have just finished setting up my Yahoo and Gmail accounts on my new iPad 3.

Settings > Mails, Contacts, Calendars > Gmail and then enter your information.

Of you can set up a gmail account as an Exchange account. I have found that this works better for me for my gmail account. You set up Google Sync which has the added bonus of keeping all your contacts on Google's servers so they are never lost. Lose your phone or get a new one that supports Google Sync and you automatically get your address book back.

There is a limitation on this with the address book though. For some reason you can't create custom telephone or address ID's on Gmail and then have them transfer to your Address book. Most of my contacts have multiple phone lines, my wife for example has two work telephone numbers that I need to keep track of and I am stuck with them both being labled work rathern than being able to identify which is which. This is an annoyance but not big enough for me to take the time to move all of my contacts into the address book on my phone and risk losing them if I were to lose my phone.

unfortunately this isnt working... but this helped
