not to mention the bull you have to go through with BES,
Blackberry tech is old....
Any data to back this up? Why does iPhone require to fetch emails? BB emails arrive instantly.
I work in an area where I support many mobile phones.. and it just seems like BB and BES is a headache and adds more layers to the whole mail setup.
Every BB connects through BIS and/or BES for any internet/email/bbm traffic. The whole purpose of BIS in the late 90s was for RIM to show the carriers that they could offer data centric device with compressed data and not hammer whatever networks were available at the time. Since then its just gotten bigger and more complex.. and I've seen first hand with many BB users that mail is not always pushed. imagine for every BB user every one of their registered mail accounts sit on RIM's network logged and consistently polling or connected looking for new mail (and eventually pushed to the phone). Can't even imagine how they handled hundreds of millions of accounts, let alone all the internet traffic from every BB. Its a mess of an infrastructure in my opinion.. adding another expensive and possible point of failure.. Why does a phone need to rely on a whole separate network for it to work Do a quick google search of people complaining how hotmail accounts aren't always pushing or how gmail accounts get delayed and still don't have proper 2 way read sync status.
The beauty of the iPhone (along with others, WM, Android, Symbian, webOS, etc) is you can simply add pop3, imap, exchange mail accounts to the phone and the phone does a direct connection to the respective server. Exchange Activesync is true push, and you get mail/contacts/calendar through it. Seems to be getting popular for Gmail users to use activesync to connect to their accounts.. also sounds like MS may enable activesync for Hotmail accounts as well.
At my one office, we have a big mix of BB and iPhones. iPhones have simple direct exchange connection, and BBs all connect through a BES server. It requires more $$, time to support, increased downtime.. NEVER an issue with activesync based phones connecting directly.
