I use the default messenger that is on the black berry curve for google talk. the issue I am having is with trying to send messages to an iPhone using the VTOK app. The VTOK app connects the user to google talk just like the app on the black berry. I can receive messages from the iPhone user on my phone but I cant send anything back. To me it looks like the message was sent but the iPhone user doesnt see the message. I then try using google talk from my computer and they were able to receive my messages just fine. What could be the problem? Thank you for your help

Which "curve" are you using? There are several, starting with the 8300 series and they have different processors, memory and OS.

You might should check with the developer of the app to make sure that it really is compatible with your specific BB model and OS.

And please update your profile to show the specific model number, not name of your current BB.

The model Curve I have is the 9300

which text app are you using. The blackberry has two. BBM and standard cell texting.

BBM is for blackberry to blackberry only. Vtok app for the I-phone uses cell texting so use the cell text app not BBM on your Blackberry.
