One of the most talked about iPhone apps this week is GPush [iTunes Link], a recently approved application that alerts you when new email arrives in your Gmail inbox.  GPush is designed to placate users who want Push Gmail, but are still waiting for Google to offer this seemingly no-brainer service to its iPhone users.  Seriously, Google – why are third-party companies having to do the heavy lifting here?

The app is fairly straight-forward; input your login username and password, authenticate, and GPush will send you alerts via iPhone OS 3.0’s push-notification system when new mail arrives.  New messages show up just like text messages in a small, semi-transparent window in the middle of your screen, with the sender and the subject line.  So far, so good.

But the application is limited to this function only; once you’ve been notified that new mail is waiting, you still have to use standard methods (web interface, iPhone’s built-in Mail app) to view your email.  And in our two days of testing, the application failed to alert when new mail arrived about 20% of the time, which could be a real problem if you are a heavy Gmail user.  The badge showing the number of Gmail messages waiting to be viewed also remains too long after mail has been viewed.

Irrespective of its limitations and intermittently lackluster performance, this is a v1.0 release, and will likely improve over time.  At $0.99, it’s also a very small investment, and is easily worth the price if you spend too much time manually checking your GMail inbox for new messages.

Whether it’s the faster CPU, the new PowerVR SGX graphics processor, the doubling of RAM or (most likely) the combination of the three, the new iPhone 3G S rips through the one app that killed my 3G: Google Earth.

The iPhone version of Google Earth [iTunes Link] was choppy and frustrating on the iPhone 3G.  The 3G S, on the other hand, handles the app quite well, beautifully rendering, resizing and rotating the satellite images with hardly a lag.

Now, many users may not care about graphics processing power (I am not much of a gamer, myself), but it’s clear that the new GPU is a marked improvement over the last model.  If you’re a gamer, the 3G S is calling your name.
