So why doesn't Apple let us use it by providing an FM radio function in the music app?

According to Chipworks,

Contained within this module is the BCM4334 which we’ve seen before in the iPhone 5. It includes IEEE 802.11 a/b/g/n single-stream MAC/baseband/radio, Bluetooth 4.0 + HS, and an integrated FM radio receiver. It is designed to be used with external 2.4 GHz and 5 GHz front-end modules, which include power amplifiers, T/R switches and optional low noise amplifiers.

I thought the iPhone had had an FM chip for years. It may be FM-band capable, but it lacks hardware support to use it as an FM radio, similar to the iPhone 3GS. That's what my research shows, anyway.

Bummer, this could have been a cool jailbreak tweak.

There are apps like iHeart radio that let you listen to virtually any radio station you want. Why not just use one of those?

Oh yeah. LoL. I forgot some people aren't unlimited anymore. I'm still grandfathered into my unlimited AT&T plan. :D

Your unlimited plan includes a slow down of data speeds after a certain amount used, so in that aspect I rather pay more if I go over than being so slow to the point of being almost unusable. As far as the FM feature, imagine a natural disaster that takes out the cell towers, now you have a nice way to listen to the radio and emergency announcements. That's just one example.

Go over the data cap and I'd bet streaming wouldn't work well when your throttled to edge.

Agreed. We're on a roll here. (y)

My unlimited data plan doesn't come with that particular feature.

A natural disaster of that scope would likely knock out electricity too. That's when a solar powered radio comes in handy. ;)

I'd rather bash a radio on a zombie than my iPhone. ;)

I have unlimited and it never slows. I use Netflix a lot on my phone. Last month I used 25 GB lol. If it did get throttled then I never noticed it. I have a military account. I'm retired and I have been with them from the start. Maybe I'm the lucky one.

I've never been throttled. Always go over 5GB. From April through July I was using my phone for everything & averaged over 30GB per month, think i hit 50 a couple times. A lot was tethering. Never throttled or any response to my tethering.

Do you get 50mbps LTE speeds?


Sent using iCafe app
Yup, got 60 in Minnesota and Michigan on T-mobile LTE. Here in Louisville, KY, their LTE is brand spanking new (just got turned on over the weekend) and I'm getting about 25 already. I don't doubt that I'll be getting 50-60 here soon, too.
