will straight talk phone service work on Iphones

No. Straight Talk is a CDMA carrier that piggy backs on the Verizon network. CDMA iPhones can only be activated on Sprint and Verizon. There is no way to get one activated on the Straight Talk network. Unless they start selling iPhones, you can't use an iPhone with their service.

AT&T already supports the iPhone. They do NOT support pre-paid service. T-Mobile in the US uses a network that is not fully compatible with the iPhone.

IF you were to purchase an unlocked iPhone, you could use it on T-Mobile, however:

3G data will not work. You will get Edge data only.

Visual Voice mail will not work.

FaceTime will not work.

MMS messaging will not work.

Yes you can use Straight talk on your iPhones. The sim card costs $14.99 and can only be ordered online. I ordered an AT&T compatable phone SIM card. You do not need to buy or use Nokia N71 card.

I have been using their service for the past two months on a 3gs phone. Locked or offically unlocked did not matter. The phone is NOT jailbroke either. The only three issues with ST that I am aware of are: no MMS on messages, no hotspot/tethering, and no visual voicemail. You do get notified of voicemail with badges and in the notification windows. The only set up required is to take safari and point to http://unlockit.co.nz to build a network configuraion file to enable data. (Voice and text work without the config file.) This site uploads a configruation file that is the same as one built by the Apple Configuration Program. The site is FREE and provides help. It does not "Unlock" your phone like AT&Tcarrier unlock or other jailbrake programs. $45 a month for unlimited talk, text, and web. I do not use international calling, but would consider skype or google voice for that. I have averaged 2.6gb of data a month with no cap on speed either.

The listing from basilfrommiddleburg does work if you follow his instructions got my data working in 5 minutes after reading his post.

The trouble I am having is low signal and the service staight talk works with is AT&T my phone was an new phone with the att sim card still in it but never activated. So it will work if it is locked to at&t from what i was told, from straight talk they just can not help you if you use a phone they do not sell and you need to buy the mini sim for i phone i ordered mine on line.

You havent found any way to receive MMS messages on the 3GS?? Thats is all I lack and I would like that capability!!!!

If I transfer the SIM to another smart phone (android) will I still have this constraint??
