How do I unlock/jailbreak an Iphone 3G/s 3.1.3?

iPhone 4 vs 3GS signal comparison

  • For people with the new iPhone 4, who previously had experience with the iPhone 3GS. How do you find the iPhone 4 stacks up against the 3GS in the area of signal reception? Is the iPhone 4 better or worse at obtaining and maintaining a cellular signal? I live in an area where the AT&T coverage is borderline. I tried the iPhone 3GS once but the signal strength was not good enough. I am wondering if the iPhone 4 has made any improvements in this area. **Please note** that I am aware of the signal reduction/attenuation when holding the iPhone but as I would use it with a case anyway I am not so concerned about it. Essentially I am looking to see if people who have used both the 3GS and iPhone 4 notice any difference in the signal reception. Thanks!

  • Answer:

    (for me 3g -->4, not 3GS --> 4) I don't see any difference in reception, but I think sound quality is slightly better

I don't have AT&T, but in for me, in Paris, the reception is better in all aspects. My iPhone 4 can maintain a 3G connections in places where my 3GS would normally drop into GPRS or EDGE, and I can maintain a connection in the metro for the most part, whereas my 3GS usually dropped to "no signal" when going between stations. Also, it resolved http://ask.metafilter.com/157450/can-you-stream-online-radio-on-your-phone-while-walking that I had with both my 3G and 3GS. The signal attenuation issue doesn't affect me at all in any real usage scenario. I can make it happen by gripping that spot on the phone with my hand as tightly as possible, but if I hold the phone normally it has a negligible effect. But I don't have any experience using it in a place with a weak signal yet (except in the metro, but that's sort of a special case).

Also previously 3G - I haven't seen any difference in reception here is Connecticut.

From what I've noticed the signal is slightly better - perhaps a half bar's worth in some areas that aren't well covered.

Previous 3G. Signal is just as crap as it ever was in my Faraday cage of an office (AT&T swears they're going to fix the "degraded" towers in the area... someday), but sound quality is actually much better and I've had fewer dropped calls since I got my 4. Now, iOS 4 did awful things to my old 3G's wifi reception, but that's another question.

I don't talk on my phone too much, I have the 4g and the 3g and I don't notice any kind of significant difference.

Doesn't really answer your question, but my wife's company got her an http://www.wireless.att.com/learn/why/3gmicrocell/ to improve reception for her Blackberry, and for the first time I can finally use my iphone in the house. I think the price is around $150, but we didn't buy it, so I'm not sure.
