email while talking

Currently i have t-mobile and using blackberry pearl (i like it alot and need the rim push email for instant notification of incoming emails); however, i cannot receive emails while talking on the phone (when i hang up they are delivered right away). Do any of the blackberry devices (8100, 8300, or 8800) and/or service providers (t-moble, sprint, att, verizon) allow you to receive email while talking on the phone (so i can immediatly address the email)?

Hey I'm not sure if this is what exactly you want to have, but may be relevant to what your requirements are, It's BB smart email viewer.

The problem with revicing the email while talking on the phone........ Most services are unable to provide both data and voice at the same time. However I do sometimes get an email while on the phone but very rare.
