No, you definitely can't use it with Verizon. Sorry. As, far as if it was a good buy, that all depends on your preferences and what you like. Good luck with the phone.

I'm pretty sure you can take the sim card out and use it like a touch. It won't work as a phone but it's a fun portable gaming/internet device.

As far as using it on a CDMA carrier like Verizon, the answer is no. Not only is it an issue with network compatibility (the iPhone 2G is GSM only) but carriers like Verizon restrict the phones they accept to an approved range of IMEI/ESN phones.

This is because Verizon is formerly a CDMA carrier. They are slowly becoming a GSM carrier but until they fully retire the CDMA network, this policy is probably here to stay. They have loosened it with phones like the 7 where Apple factory unlocked ones are accepted, but you can't unlock an AT&T iP7 and expect Verizon to accept​ it. They even have a restriction on Prepaid (Phone in a Box). These phones are locked and they cannot be used on postpaid for 1 year from activation. That's the only time they will allow users to unlock them and use them on the postpaid network.

Not only that, but they also refuse to fully unlock their iP4s. On the 4s, the GSM half remains locked, even if you get Verizon to unlock your phone. The iP5 has factory unlocked GSM, but that's because the FCC do not allow them to lock it.

As far as it being a useful phone you can use every day... I'm going to say no. EDGE networks are on the way out. At this point, the 2G is more of a shelf item.

I printed out this page (HT3406), took it to ATT so they could switch my old SIM out (from 3g back to the original iPhone). Did that. Still could not get iTunes to recognize the phone without going through an ATT activation process. Went back to ATT and was told that my phone was "bricked" and need to be "un-bricked" and that they could not do that in the store. ATT lady said, "Call Apple". According to lady at ATT since my SIM card was moved to new phone it would no longer accomplish the goal as stated in support doc. HT3406. Thought about calling Apple but they want $30 for a phone call. So I still haven't given up doing it on my own.

For what it is worth.

I have a 1st gen iPhone left over after I upgraded to 3 g. I would really like to use its wifi capability for misc. internet and games (call it an iPod touch).

I was stopped by itunes when I plugged it in but was stopped because I didn't have a sim card. I bought a sim card from ifixit.

Next I was stopped by the activation screen of itunes. Itunes won't let me in to do anything with the device without activating with AT&T. I don't want to do this because I don't need phone capabilities and don't want the expense (minimum 2 year commitment).

Paid for a jailbreak program, downloaded, then got lost in a sea of other sites, other downloads, confusing steps. Needless to say not the 5 minute fix the site advertised.

Seems like a waste to not be able to get some use out of this neat little pocket device. It goes against a core value of ifixit, "waste not"

Good luck. I will drop elais a email
