iPad 3G Disassembly, 3G Video Streaming and GPS Improvements

[E.Lizardo]

If you tend to carry your phone in your back pocket I suspect many people will be calling it broken a$$ plate.

Pretty sure it's ceramic not glass and break resistance won't be a problem.

Frankly, nobody cares what you like or don't like.

Nobody cares what you post about what nobody likes.

Nobody cares what you post about nobody caring what he posts about nobody caring about what he likes or doesn't like.
So there.

Yes, chip on full-size card has almost the size as micro-sim card, so it is fine work...

Are you saying you cut a full-size sim card and shoved it in the micro sim slot? If so, lol.

I just have to know what all these website are ...

Well... every single website except for the new york times and cnn.

No.You just have unassisted GPS.

Not necessarily. To get a first fix a GPS receiver not only needs to know its own (rough) position and time but also the current positions and movements of the satellites. Ths changes constantly and is called "almanac". This data is broadcasted by the sats every 40 seconds and so it can take up to 79 seconds to pick up that data. It is valid for the next for hours, so a GPS chip can fix very fast if it has been used during the last four hours.

There is a form of assisted GPS that works by giving you the almanac data over a faster channel. The data can also be extrapolated for the next week or so. On a powerful device (Notebook) this could be done locally but it would take too much time and battery life an a smartphone like device. But since this data is only a few kb it can be easily calculated on a server and distributed to many users. For example several TomTom devices have much improved first fix times if you connect them to a computer once a week. (This will download GPS almanac data to the device).

So an iPad could have much better GPS startup times even if it is only connected to WiFi every few days. But I don't know if Apple makes use of that.

It's not my iPad so there would be no tears.The people who took it apart knew and accepted the risk of breaking it.
It's not the frickin' Mona Lisa,its a product that will be made in the millions.
Quit whining.

not whining, just commenting, thus the purpose of forums, not being rude!

Yeeessss.SJ did say it was magical,but it can't magically download maps without 3G or Wifi.Did you really think otherwise?
However,purchase a nav app and the maps will be stored on the device.No data connection needed.

I wish it had maps already. It would be so much better if it had an SD slot or something to allow taking cards with maps on them... Oh well. That leaves Apple a fantastic new feature for the next version... The nice thing about no slots is that slots tend to get stuff in them like lint, etc. I remember my Palm getting stuff in its slot. Who saves the dummy slot fillers anyway...

My Garmin has issues if I leave it off for too long and then the first time I turn it on is in another geographic area. It freaked in Dallas after being off for a month and last used at home in Michigan. It took a rather pronounced amount of time to display where I was (15 minutes+) but after that, it was spot on. It was evidently downloading the 'almanac' and once updated was fine.

They are handy, but you have to keep them up to date to make sure they work as designed. When it's up to date, it locks on to the GPS network very quickly.

But for some, if it works great for them. More power to them.

My family is scattered all across the country (and some abroad). I use the built in iSight all the time to chat with them. Sometimes we connect L.A. to NYC to NC to PA at the same time. It's pretty fantastic actually. It makes a phone seem dreadful.

I would love if the iPad had an iSight. But in a way that's not really the point of the iPad. It's a media consumption device above all else.

That's insanely rude.
