Galera possou 2 aparelhos um N95 com GPS interno e um i570 Nextel tambem com GPS Interno, gostaria de saber como proceder para utilizar o GPS Interno destes aparelhos, consigo hoje utilizar um GPS externo via Blutooth, fazendo a conexão e escutando via Stream as posições, proximo passo que gostaria de estudar seria a conexão com o proprio GPS do aparelho.
Obrigado!
Você pode utilizar a api location, a Nokia e a Nextel tem bastante conteúdo sobre isso, dê uma procurada no site deles.
Hum, eu andei mexendo nela, mas achei que era uma api para se manipular as geo posições, ou seja achei que era soh para mexer com as informações não para iniciar GPS, e tal. Vou dar uma estudada a respeito! Obrigado
Aproveitando o tópico, como vc capturou as posições por bluetooth?
Tbm tenho um receptor bluetooth GPS e vou precisar fazer o mesmo esquema 
segue ai os codigos, 3 classes faz o trabalho, a primeira eu coloquei os endereços dos dispositivos fixo, ai é só vc alterar os endereços para o seu dispositivo.
