Apologies - just sent this to the apple-iPhone list incompletely by accident. Here's the complete query: While we're on the subject, I'm about to buy a replacement refurbished iPad after having my iPad1 stolen. What is the first model or generation of iPad to be able to take advantage of a 4G cellular network?
Thanks,

Not related as I am in NZ, but we have a Cat4 4G network, Cat4 giving a max 150/50 while cat3 offers up to 100/50

I've had 97/26 on my 5S, which is a Cat 3 device.. Thats not uncommon as apparently, getting close to max speeds is not hard, it is very possible providing distance and congestion are favourable. I get 36/9 at home and that only on 2 dots of 5. It seems LTE speeds are real rather than chiefly theoretical

Jim,
Thanks for your reply. I asked the original questions just because we noticed my son's cellular service always says 4G on his 4S which I had never seen on my iPhone 4. According to your reply, it sounds like a marketing tool rather than reality. Just out of curiosity, what to your knowledge are the maximum download speeds people find when using 4G/LTE on a current iPhone 5/5S?
Thanks,
Dick Johnson

I have an iPhone 4, and my son a new 4S for Christmas. Mine is always on 3G and his on 4G when there's no wifi. Two questions: 1) was iPhone 4S the first iPhone to allow and use 4G cellular? 2) is there any change of settings that would allow my 4 to use 4G?

The first iPhone with a cellular chip/radio capable of utilizing the LTE network was the iPhone 5, not the 4S.

Neither an iPhone 4 nor a 4S can be made to utilize the LTE network; that would require a chip/radio they do not have.

Keep in mind that "true" 4G is not what the sales-droids claim it is:
In March 2008, the International Telecommunications Union-Radio communications sector(ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) for high mobility communication (such as from trains and cars) and 1 gigabit per second (Gbit/s) for low mobility communication (such as pedestrians and stationary users).

Even now, no US LTE provider gives you even 100 Mbits/s, let alone ten times that.
