@faizpsp89,
It's definitely NOT true because to-date Maxis hasn't made any official announcement on the i3GS. SingTel however does allow the upgrade

@faizpsp89,
The information is available on the SingTel website, or if Ur too lazy to go into the website, then check out the iPhone 3GS SingTel Official Thread.

Please don't expect to be spoonfed here!

@sanzo86,
Both SingTel & Maxis sets are UNLOCKED sets which means it's usable worldwide on any foreign SIMS. As to JB, if U wanna JB it U still can except it voids all warranty [but if U do decide to JB and if something happens to the phone, just do a full restore before U go claim ur warranty]

@hokkianu,
Some people just wants to JB it; be it so they can customise settings, etc.

@sanzo86,
I believe the SIM will work but only for data. U will not be able to use the voice/phone functions with that Maxis BB SIM.

@sanzo86,
Y don't U cancel the Maxis BB and open Unlimited data plan on your voice SIM; that way you still can Internet Tether through ur i3G/i3GS when U need to, and when U don't u can still use ur i3G/i3GS to do whatever U want

@hokkianu,
People have different needs. Also, forummer raoul did caution about battery lifespan when using iPhone to Internet Tether - I read that on one of the other discussion threads earlier but I dont use mine often enough to have to worry - my Internet Tethering is really only for emergency purposes onli

Also, I gather from the few responses is that people just wanna go for the iData plans and iValue plans because there's a 'rebate' on the price of the phone. To me, I don't think I be using it lah so it's penny wise pound foolish kinda scenario

@sanzo86,
Ah well.. in that case U will then need to keep swapping SIMS. Meaning, if U don't want to pay for any data charges on ur Voice enabled SIM then U just have to disable APN when ur Voice SIM is in the i3GS.

When U think U wanna surf the net or check stuff online, then swap SIMS and use the data services one. From what I can tell it will be utmost inconvenient but it's your call

@z3171600,
Yes it is possible; U just need to activate multi-SIM feature with Maxis.

@maryjane9996,
The biggest difference is in the speed. If U haf the budget go for the i3GS instead of the i3G. I upgraded from the i3G to i3GS and have had no regrets

@maryjane9996,
I'm not sure about the USD versions and if U need to sign a contract but you're right, if it's USD399 it's a good price. The only thing U'll haf to bear with is that U'll have to unlock ur i3GS.

@DigitalTech,
That information is available on the net if U would only choose to look for it. Anyhow, comparing the US & Australia i3GS the US sets are cheaper but I don't believe you're able to purchase an outright unit without signing onto a plan.

Also, the US units are locked sets as compared to the AU units.

@diners,
We believe we don't have that particular code in our "database".
