Look what I got in the email from the interwebs..

We are writing to you to let you know that in the next 24 hours, your Truphone for the iPhone application will be automatically upgraded with some exciting new features*!

These new features are:

1. Instant Messaging (IM)
IM will be added, meaning that you can have two-way IM conversations with MSN Messenger, Yahoo! Messenger and Google Talk users.

2. Google Talk Calls
You can now make and receive calls using Google Talk.

3. Twitter Integration
Recently launched, if you have a Twitter account you can tweet to your heart’s content, and see your friend’s latest tweets.

Interesting. With Gtalk and skype, I think this will push Truphone and ‘THE’ VoIP app for the iphone.  Here is the rest of the email.

And that’s not all. We also plan to introduce Skype calling and IM on the Truphone for the iPhone soon.

You can start using IM by following these simple steps:

a) Tap the ‘IM’ or ‘IM/More’ screen in the Truphone menu bar

b) Select ‘Setup’

c) Select the type of IM account you want to setup (GTalk, MSN and Yahoo!)

d) Enter your account details and sign in

e) Press the ‘Back’ button on the top left of the screen

f) Select ‘Friends List’ and then tap the required IM tab

g) Check that the friend you wish to chat to is online (their icon will show as green in the display), and start chatting away

You only have to do steps A to E once for each type of IM account. Entering the ‘IM’ or ‘IM/More’ screen after this will sign you in automatically.

To make Google Talk calls, select Google Talk, select your Friend from the Friend List, and then select the call icon.

Instructions on using Twitter can be found by selecting the Twitter ‘t’ icon in the ‘Tru Friends’ screen.
