Please log in for more thread options Nope - as I've stated, the secure HTTP-based Push protocol is written so
that it minimizes traffic. This means it employs a "heartbeat" (some 300
bytes) only exchanged every 5-10 minutes. This means the *additional*
traffic (in addition to the standard "keep alive" traffic of active GPRS /
3G connections) introduced is minimal.
Again, you don't need to be afraid of this - Push Mail is by far the best in
this respect - much better than, say, a periodical mail check every, say,
minute.
