Another configuration to consider:

1.Buy the Storm from elsewhere at around 1.8k-2.3k

2.Sign up Celcom P148 plan : You can make RM148 worth of calls, sms, mms and also unlimited 3G.

3.Pay for BIS license at RM30 per month so you will have full functionality of the Blackberry.

4. So total damage per month is around RM180.

For me, my average phone usage is around RM150/ month so this plan suited me perfectly. Furtermore I only use the BB as my tethered modem to surf. In my area (damansara), I download file via Rapidshare and I can easily get more than 200KBps (not Kb).

As for the Maxis plan, the BB data plan and phone plans are separated. Hence Minimum to pay is RM250/ month to have the above configuration. In my opinion, if it's the iPhone, go for the Maxis iValue plans but for Blackberry, the obvious choice is Celcom plans.

PS: I personally like both the blackberries and iPhone a lot
