Google has provided a mechanism for iPhone users to get Push Email functionality. Apple is still dragging it’s feet for allowing the iPhone to support it natively, so Google has enabled mail to be synced via the ActiveSync mechanism that is available on the iPhone.

However, there is one limitation. iPhone users that already have an ActiveSync account enabled (e.g. for work email) will not be able to use this option. This is because Apple only allows a single ActiveSync account on the iPhone. This is an Apple limitation, not Microsoft or Google.

Lifehacker had a great summary article about how to access GMail when they are experiencing problems, such as earlier this week. The article goes into detail but there is a summary of links:

• Plain HTML version
• Safe Mode
• Old Version
• Without Browser Check
• Mobile Version
• iPhone Version
• iGoogle

The new version of iPhone firmware is out. Don’t upgrade if you are jailbroken and/or unlocked as this will probably lock you out until it’s cracked by the “iPhone Dev Team”. Use iTunes to get the latest update if you have a legit phone.
