iPhone OS 2.1 beta reveals possible turn-by-turn directions
Posted 25 July 2008 @ 9am in News
Apple has released a beta edition of iPhone OS 2.1 along with an accompanying, updated SDK. The new SDK makes a few API changes that could indicate the addition of turn-by-turn directions in Google Maps or third-party applications. Reportedly added to the CLLocation (CoreLocation) library are:
- CLLocation.heading
- CLLocation.speed
- CLLocation.speedAvailable
- CLLocationDirection
- CLLocationSpeed
Greg Joswiak, Apple’s Vice President of Marketing, has refuted early assertions that GPS-based driving directions on the iPhone 3G are impossible because of the GPS receivers’ size. The iPhone’s GPS is “just like the GPS in other phones, many of which do provide driving directions,” but there are some “complicated issues” preventing driving directions at present “It will evolve. I think our developers will amaze us,” Joswiak said.

Never mind GPS, where is the 3G reception? I bought a new iPhone and am paying more per month for a feature that is, at best, half-ass. If the 3G chip IS defective, will there be a recall? And if that happens, will we have to pay AT&T while we are out our iPhone? Or, will we be able to exchange for a new iPhone? This is beginning to look like a BIG snowball.

3G in general, often requires a higher operating frequency thus is more susceptible to interference or lack of line of sight to the cell tower. I’m testing 2.1 and I think they have addressed the 3G-2G handoff issue under poor coverage.
FYI: Carriers have made great improvements so their service works reliably indoors in most areas, but by no means they intended to have such service as indoors it was conceived as an outdoor mobile solution.
In my area 3G coverage is spectacular. Give it some time as 3G is new to the USA and the technology and network coverage is very promising.

Movieman 1942,
I completely agree…I had an iPhone 2G and it was extremely reliable. So I decided to “Upgrade?????” to a 3G and I have had nothing but problems. I have had no signal with 3G several times and it doesn’t switch over to 2G or to Edge like it’s supposed to so I’ll look down and I’ll notice that my phone just says “no service”. Who knows how long I go without phone service??? So now I spend most of my time with the 3G turned off (doesn’t that mean I didn’t need to buy a new phone???) Oh, and when I’m on 2G now, my “bars” are not half as strong as they used to be. So, even though I used to be a major promoter of the iPhone, until they come out with a way to solve this problem…they have lost my endorsement…I wish I could take it back and start all over again.

Patience, my friend, is a virtue. You should know that esp. since you jumped ship without waiting for reviews & firmware bug fixes.
